Prosthetic leg for amputees designed by Jae-Hyun An to encourage new genre of ballet

Pratt Institute graduate Jae-Hyun An has made a prosthetic leg that permits amputees to carry out ballet like never ever just before.

Unlike normal synthetic limbs, which might be created to mimic the human human body, the Marie-T allows amputee ballet dancers to reinforce their functionality.


Produced up of 3 factors, Marie-T includes a weighty foam-injected rotational moulded foot, with a stainless-metal toe and rubber grip that help provide the dancer with harmony and momentum throughout rotations.

In mainstream ballet, dancers typically move in and out of the pointe position – when all body weight is supported by the tips of fully extended feet within pointe shoes.

On the other hand, due to huge pressure to the foot and ankle of a performer, it is actually unattainable for any ballet dancer to consistently complete in this posture.


Jae-Hyun An, who analyzed within the Pratt’s Industrial Style and design programme, designed the carbon-fibre Marie-T to enable amputees to dance on pointe all over a performance.

New York-based An said the design, which is named after 19th-century Swedish ballet dancer Marie Taglioni, could encourage amputees to develop a new choreography that has never been achieved by mainstream ballerinas.


“I needed to examine what would come about if you may permit a person to execute on pointe 100 for each cent of the time,” explained An, who formulated Marie-T about the training course of 4 months.


“How would ballet improve? I required to produce a Software for someone to just take and Enable their creativeness define the capabilities of the product.”

During research, An realised that a weak ankle can twist and cause a ballerina in pointe position to wobble. In response, An designed a strong and stable ankle area that helps the ballerina stay in balance.


The ankle connects to a slightly curved carbon-fibre limb which assists take in the shock from the impression in the ballet dancer stepping ahead. The limb is topped by a 3D-printed socket with steel round head screws.

Ill-fitting prosthetic limbs can result in blisters and rashes on dancers, so An built the Marie-T so which the parts is often effortlessly switched out when they develop into very well worn or need to be resized.


The designer explained to Dezeen: “Prosthetics by alone is these types of a powerful and inspirational structure. Any sort of it is absolutely awesome! Whether it’s Hugh Herr’s bionic legs within the Biomechatronics Group in MIT, or perhaps the Flex-Foot Cheetah Leg from Ossur, or perhaps a peg leg from… whenever.”

“It is inspiring because the technology is incredible but even more so because of the immense struggle an amputee has to overcome to use these products. Some argue that some of these prostheses give amputees a certain advantage in specific tasks, but I am not sure they would say the same if they ever saw how much training and care it takes to handle a prosthesis,” he continued.


“In my investigation I found Viktoria Modesta and he or she re-interpreted overall performance with her prosthetics. It was visually so strong and opened a completely new location of prosthetics for me. I fell in love with the idea of building something that could develop the creative and cultural scene of a Group with prosthetic people.”

To continue developing this project in the future, An hopes to collaborate with an amputee dancer who has their own vision for prosthetic ballet.


“The look of the prosthesis will modify to suit the dancer, but additionally to match the precise actions from the recently developed choreography,” he spelled out. “However, till I meet up with this dancer, I’ll keep on to establish as a designer.”

Other developments in prosthetics this year have included a newly developed electronic skin that is able to mimic the function and properties of human skin. Scientists believe that the skin could help to create prosthetics capable of providing sensory feedback.

Meanwhile engineers from MIT have made a streamlined prosthetic foot that allows wearers walk having a fluid motion, and can be manufactured at a low priced.
